On April 4, 2022, the federal government stopped using the DUNS number to uniquely identify entities. Now, entities doing business with the federal government use the Unique Entity ID created in SAM.gov. They no longer have to go to a third-party website to obtain their identifier. This transition allows the government to streamline the entity identification and validation process, making it easier and less burdensome for entities to do business with the federal government.
The Integrated Award Environment manages several systems, including SAM.gov, FPDS, eSRS, FSRS, CPARS and FAPIIS. All SAM.gov registrants have been assigned their Unique Entity IDs and can view them in SAM.gov. To learn more about this transition, please see the information below. Join and follow our community on Interact to be notified of the latest news and information about changes happening at IAE.
If your entity is registered in SAM.gov today, your Unique Entity ID has already been assigned and is viewable in SAM.gov. This includes inactive registrations. The Unique Entity ID is located on your entity registration record. Remember, you must be signed in to your SAM.gov account to view entity records. To learn how to view your Unique Entity ID go to this help article.
Refer to the Guide to Getting a Unique Entity ID if you want to get a Unique Entity ID for your organization without having to complete an entity registration. If you only conduct certain types of transactions, such as reporting as a sub-awardee, you may not need to complete an entity registration. Your entity may only need a Unique Entity ID.
If you operate a system that connects with IAE systems, documentation about using APIs to access SAM.gov is found at is open.GSA.gov. The latest version of FPDS ATOM feed includes the Unique Entity ID.
Agency system owners are encouraged to join the Technical Interface Community (email IAE_Admin@gsa.gov to join).
The Unique Entity ID is the official identifier for doing business with the U.S. Government as of April 4, 2022.
The process to get a Unique Entity ID to do business with the government is now easier. You go to a single place, SAM.gov, to:
The change we made creates predictability for the cost of entity validation services. By separating the government requirement for a Unique Entity ID from the government requirement to validate that the entities are unique, we introduced competitiveness into entity validation services. We then competed and awarded a new contract for entity validation services that is not connected to the identifier itself. We chose to have the new, non-proprietary identifier both requested in and generated by SAM.gov to reduce the burden of change; the transition in identifiers only needs to happen once, even if in the future a different entity validation service provider is selected.
The definition of what makes an entity unique is not changing, however.
If your entity is registered in SAM.gov today, you already have your Unique Entity ID and it is viewable in SAM.gov. This includes inactive registrations.
All other IAE systems — CPARS, FPDS, FAPIIS — currently display and accept the Unique Entity ID
